问题：移植EtherCAT从站代码，代码中带有巨多的__attribute__((aligned(1), packed))宏定义，在CCS6.1上也勾选了GCC选项（Build->advanced options->language options->enable support for gcc externsions）,重新编译后仍旧存在如下提示：
\EtherCAT\include\esc.h", line 167: error #1167: invalid attribute for "struct <unnamed>"
难道C2000不支持__attribute__编译么？？
10#：
可以把167行附近的代码都贴出来看一下吗？另外，编译器版本是多少？

具体哪一行是176行呢？要将报错信息与相应的代码对应起来呀。

OK, C2000不支持单字节对齐，请参考这个帖子最后两个回复：
